" Ravena. :in the county (it-Albany and Sta-te "of New York,` have.inventedlcertain new and 'useful In'iprovenients in Metallic Railway -nietalli'cra-ilway tie which will not 'louck1e` Ties, of'whieh the following is a' specification.. 4 A i My invention theobjectof inyinventi'on is toprovide a or bendA in the center, that" will provide' a.

resilient" seat for-the" rail, andlsafe and se` eurenieans torlioldingthejtie uponthe'raili5' road and the 'railiipon'the tie, and will fb'ei practicalfin operation and simple and ec'ononiical inI construction. I` obtain these objects byl means of a metallic railway tiev constructed as fshowii in the accompanying drawings. in which-f` y Figiire 1v is a plan View of niy tie with the is a side elevation ot the saine with one end thereof in section "on the linesA X of Similar vletters refer f-t'osimilar parts throughout' the several .Views v.Referring to the" drawings, T repr' ents iny metallic tie which is preferably con- 3()` strueted ,of steel of suitable length to reach under both 'rails of the track, leaving suiticient space fior clamping itdownand having sutlicie-nt breadth and thickness to furnish strength and rigidity.

- the tie under the rails; T hese bed-plates are' inade of suitable width and length to properly 4siipp'ortftlieti'e and the weight of the vi p rails with the cars upon the rails. .Fliese bed-plates have the ends F, F extending downward into the ground at obtuse angles,' as shown in Fig.V 2. and theseends tend to ,'prevent the bed-plates from sliding upon the ground and also being'at obtuse angles when the trains pass over them causing the bed-platesto vibrate, the ends will gather dirtnnder the bed-plates and th'us tend to tainp the railway bed.

The'bed-plates P, l) are. proyid'edwith shoulders p, y? on theends toward the center of the road bed for the tie to rest upon. Also loops, G, G on the same ends for the tie to slide through and the shoulders E, E upon the other -end o f the bed-plate forthe. end Vof the tie to rest upon and to be fastened upon.l

relates to .railway ties andallow for a spring downward of y y u when heavy trains are passing over it. rail'R clamped uponitiin position. Fig. 2"

P, P are bed-plates to support the ends off NIN,

' over which the rail rests are liollowed out or depressed lso-as to forin a recess or chamber under the. tieso that the tie does not Colne in v.

contact with the -upper s'uiitaee of thebedplates directly under the rail, but rests upon the shoulders 2) and E and nader the loop G. In this depression or i:ecess. I 'place a convexe-concave spring plate S which hassuflcient convetity and is so constructed .that

vthe upper surface will bear against the under l surface ofthe tie vdirectly under the rail and the. ends 'bearagainst the upper surface of thel'ied-plate,` asshown in Fig. 2.' The plate ,S vshould -be made of suitable inaterial-of sui'licient thickness and strength to allow aslight resiliency lto' the tie when 'the train passes over it.- There should be' asutlicient -vacaney 'Szbetween the centerl of the spring plate AS-and the bottoni `of the'bed-plate to H is an opening in the centerbf the bedplatein the depression ',undery the'rail'to al? low any acuinulatioiiof nioisture'toescape.' C. C are clainpi'iig plates to tasten the rail upon the tie.4 These plates extend slightly over the-edges ot the flanges of the rail and are provided with holes by which the 'threaded bolts may be used to attach thein to thel tie, as shown in the drawing.

the tie' The extreme ends of the ties are preferablyovert ie hollow projections, o in the shoulders E. E andthe ties inay also be securely fit over these projections loosely so as to provide for thel vibration causedby the cars provided with holes which fitloosely" passing over the ties. and bolts extend upward throughthese projections and through thel'ioles in the ends of the tie and the ties are thus bolted upon theshouldei's ot the bed-plate.`

Constructed in this way the ties may be .ot any suitable 'thickness and strength and are attach-ed securely to the bed-plates. The rails are attached to the 'ties in'siich a 1nannerthat theyniay bewatched and the bolts lteptproperly tightened from the sui-tace..

ot the railway bed. yThe spring plates under the rails niaybe of siichstrength as to giye the proper"resiliency to the seat of the rails .when the ears pass over them. The bed-- The central portion oit the bed-plates P, P iv plates being embedded in the ground will hold the rails in alinement andthe whole road bed thus provided would be safe and secure against accidents. The -material from which the Whole structure is composed isl practically indestructible and will last a generation.

What I claim as my invention and desireV to secure by Letters Patent is,

1. In a metallic railway tie, a metallic bar adapted to extend across-,the track under the rails, bed-plates adapted to support the ends vof the tie, said bed-plateshaving recesses under the tie, a convcXo-concave metallic spring plate in each of said recesses under the rail and adapted to supply la resilient-seat to the rail upon said tie.

In a' metallic railway tie, a metallic bar v adapted to extend across the track and sup- 3. In a metallic railway tie, a metallic .bar extending 'ac-ross the track under the.

rails, metallic bed-plates adapted to support the ends of the tie, lugs on the upper sur-A Y face of said bed-plate near the end toward the center of the track, adapted to sustain said tie, loops upon'the upper surface of said' bed-plates adapted to receive said tie .when resting,- upon said lugs,l shoulders at the outer ends ot'thesaid bed-plates` adapted to sustain the end of said 'tie and to which said y tie is adapted to be attached, recesses inthe upper surfaces of said bed-plates under said tie, metallic convexe-concave spring plates adapted to t 1in said recesses, the ends against the bottom thereof and the vertices against the under surfaces of said ties under the seats of the rails, thereby forming resilient seats for the rails and means for clamping said rails upon said bed-plates, Isl'ibstantially as described..

4. A metallic railway tie consisting of a metallic bar adapted to extend across the track under the rails, a metallic bed-plate adapted to support one end of the tie, a recess inthe bed-plate under that portion of the tie upon which the` rail is adapted to rest, a hole in the tie near the end thereof, a projection upon the bed-plate near the outer end thereof -adapted to lit into the hole in said tie, means for'clampin'g said tie upon said bed-plate and thera'il upon the tie, substantallyas described.

lIn testimony whereof I aflix my signature in presence of two witnesses.
